## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cryptyx-market-history-daily-ohlcv-17a4992a
```

Example prompt: Can you pull the daily OHLCV price history for BTC from CRYPTYX for the last 90 days so I can see open, high, low, close, and volume for each day?

## When to prefer this

Use this endpoint when you need raw daily OHLCV price data for a crypto asset as the canonical spot price feed for CRYPTYX-based analysis — especially when computing or verifying CRYPTYX factor scores, regime classifications, or signal metrics, since all CRYPTYX analytics are derived from this same underlying dataset.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty dataset
- Requesting more than 365 days exceeds the maximum lookback and may return an error
- Missing required asset parameter causes a 400-level error
- Payment not received (x402) results in a 402 Payment Required response
- Network or upstream CoinMarketCap data unavailability causes a 503 or empty response
